There are three semicircles in the lower left corner of the hotel wifi

What you want to ask is why there are three semicircles in the lower left corner of the hotel WiFi? The reasons are as follows:

1. Save the time of entering passwords. Using the WPS quick connection method, guests only need to press the WPS button on the back of the router to connect to the WiFi network in a short time.

2. Ensure the security of the WiFi connection. The WPS connection method uses a short-term wireless data transmission method. This method will automatically close after the connection is successful, ensuring that guests will not suffer any damage when connecting to the WiFi network. Undesirable threats of cyber attacks or information theft.
